After rebooting the server, the SSH failed to start up. Which blows because that's the only way I know how to execute commands (via Putty). When I plug in a monitor/keyboard, the monitor just says "No signal". If I reboot the server, I just get to select which version of debian I boot (currently 5.10.0.bpo.5-amd64), then the screen displays some MCE errors and then goes blank. The server runs fine, I can access through the webUI, Jellyfin runs, etc, but I can't restart SSH.
The comments that OMV gives me say
"Job for ssh.service failed because the control process exited with error code.
See "systemctl status ssh.service" and "journalctl -xe" for details."
I have no idea how to execute those commands because I don't have access to a command line. Any help would be appreciated as I'm not sure where to go from here.
